In many cases, state law allows drivers to pass bicyclists, even on roads with a double yellow line or no passing zone, provided that the bicyclist and vehicle are going in the same direction, the driver provides four feet of clearance or is entirely in the left lane, and the bicyclist is not turning left or signaling a left turn. Other limitations on passing are outlined in General Statute 20-150. This does not include any restrictions due to local ordinances.
